A method of wireless communication includes repeatedly transmitting, from a mobile device to a communication node, a first message using increasing power levels for initiating a two-step random-access procedure until a termination condition is met. The first message includes a payload part and optionally a preamble sequence. The termination condition includes (1) the mobile device receives an indication from the communication node that the payload part was received successfully, or (2) a number of repeated transmissions reaches a threshold.
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method of claim 1, wherein the termination condition is met when receiving an indication indicting a successful reception of the payload part from the communication node.
6. The method of claim 1, wherein the first counter and the second counter are initialized after the reselecting of the preamble sequence.
7. The method of claim 2, wherein the indication indicates the NACK or the dynamic grant within a same channel occupancy time (COT).
8. The method of claim 2, further comprising, after receiving the indication, performing, by the mobile device, multiple listen before talk (LBT) attempts according to the dynamic grant.
9. The method of claim 3, wherein the time-domain response window is configured by the communication node for the mobile device.
14. The apparatus of claim 10, wherein the termination condition is met when receiving an indication indicting a successful reception of the payload part from the communication node.
15. The apparatus of claim 10, wherein the first counter and the second counter are initialized after the reselecting of the preamble sequence.
16. The apparatus of claim 11, wherein the indication indicates the NACK or the dynamic grant within a same channel occupancy time (COT).
17. The apparatus of claim 11, further comprising, after receiving the indication, performing multiple listen before talk (LBT) attempts according to the dynamic grant.
18. The apparatus of claim 12, wherein the time-domain response window is configured by the communication node.
